       remctl_command, remctl_commandv - Send a command to a remctl server


       #include <remctl.h>

       int remctl_command(struct remctl *r, const char **command);

       #include <sys/uio.h>

       int remctl_commandv(struct remctl *r, const struct iovec *iov,
                           size_t count);


       remctl_command() and remctl_commandv() send a command to a remote remctl server.  The
       remctl client object r, created with remctl_new(), should have previously been passed to
       remctl_open() to open a connection to the server.

       remctl_command() takes the command as a NULL-terminated array of NUL-terminated strings
       (the same layout as an argv array).  This function is most convenient when passing simple
       text commands.

       remctl_commandv() takes the command as an array of iovec structs of length count.  This
       function is most convenient when passing arbitrary data to the command, since the iovec
       struct takes a pointer and a length for each chunk of data.  See writev(2) for the layout
       of the iovec struct.

       To control the network timeout for sending the command, see the remctl_set_timeout(3)

       After calling one of these functions, call remctl_output() to get the results of the


       remctl_command() and remctl_commandv() return true on success and false on failure.  On
       failure, the caller should call remctl_error() to retrieve the error message.


       These interfaces have been provided by the remctl client library since its initial release
       in version 2.0.
